S-141 4-step sequencer (semitone quantized) for Eurorack / Doepfer A100 system.

It can work in 4 modes (selectable by internal jumpers, two grouped jumpers):
– clock + reset (top jack = clock, bottom jack = reset. Rising edge of reset signal moves seq instantly to step 1 or to step 4, setting by standalone jumper just behind top input jack) – no jumper set
– clock + direction (top jack = clock, bottom jack = direction. Active gate „direction“ reverts sequence to 4-3-2-1-4-…) – top jumper only
– CV + confirm (top jack = CV, bottom jack = confirm.Rising edge of confirmation gate changes step according to CV „address“) – bottom jumper only
– CV + disable (top jack = CV, bottom jack = disable. Sequence is held at current step while gate „disable“ is active) – both jumpers set

Mode jumper settings (two grouped jumpers): no jumper set = clock+reset, top jumper set only = clock+dir, bottom jack set only = CV+confirm, both jumpers set = CV+disable
Third jumper (standalone jumper): works in clock + reset mode only, sets reset behavior – “reset to first step” (jumper set) or “reset to last step” (jumper removed)

Top input jack receives trig/gate/clock/CV signal (depends on selected mode of operation), bottom input jack is for trig/gate according to mode selected.
Thresholds (in CV address modes): negative to +1,2V = step1, +1,2 to +2,5V = step2, +2,5V to +3,8V = step3, above +3,8V = step4
CV output range 0-5V.

Width: 4TE/ 4HP/ 20mm
Depth: 45mm /1,8″ max.
Current: 25mA (no need for +5V supply)
Power cable included

Double check power connection before powering your system please.
„Red strip“ means -12V connector side in Eurorack standards.
In some power distribution systems connector key can be reverted.
In this case cut connector key and plug power connector right way (with respect to red strip) or use different power cable appropriate to your power system.
